How this service works
Crypto, AI, Social Media, Finance, Weather, Tools & more. Pay per call in USDC on Base. No API keys.
Output
Returns a GeoJSON polygon or multipolygon representing the geographic boundary of the reachable area (isochrone or isodistance contour) from the specified origin point, based on the given travel mode and threshold.
Example use cases
Real estate search radius mapping
“Show me all neighborhoods within a 15-minute drive from this address so I can see which areas are actually commutable for my clients.”
Warehouse delivery coverage analysis
“I need to visualize the delivery zones my warehouse can cover within 45 minutes by truck — create a polygon I can use to show customers our service area.”
Transit accessibility for apartment hunting
“Find the polygon of places I can reach within 20 minutes using public transit from this train station — I want to see my realistic commute zone before picking an apartment.”
Technical details
Endpoint
POSThttps://nexus-api-peach-nine.vercel.app/api/geo/isolineWhen to prefer
Use this endpoint when you need to compute reachable-area polygons (isolines, isochrones, or isodistance contours) for mapping, logistics coverage analysis, real estate search radius, or travel-time visualization — especially when paying per-call via USDC on Base with no API key setup required.
Side effects
- Invalid or unparseable location input returns an error
- Unsupported travel mode causes a bad request response
- Threshold value out of acceptable range returns validation error
- Geocoding failure if address cannot be resolved to coordinates
- Timeout for complex routing calculations in dense urban areas
